"Because if a consultative physician or mental health professional suspects that you are not giving an honest portrayal of the limitations caused by your mental condition, your claim stands a good likelihood of being denied. And once there is a notation of malingering in your disability case file, it will be hard to win your disability claim if you have to use the Social Security disability appeal process."

BTW, refusing to take tests or cooperate in evaluations ordered by SS is considered a sign of malingering, so that would have been just as bad.
